Abstract
The utility model provides a built-in type long term leakage-proof device, which is used for the installation of draining pipes for buildings. The utility model is characterized in that the utility model is composed of an inner cylinder 3, a funnel-shaped flange 4, an up outer cylinder 1, and a low outer cylinder 2, wherein, the funnel-shaped flange 4 and the inner cylinder 3 are once formed; the upper part and the lower part of the up outer cylinder 1 which is connected with the flange 4 are positioned on a same shaft; an outer wall of the up outer cylinder 1 is provided with a concave and convex sealing ring 7, and the lower end is drilled with a drainage opening 5 along the circumference; a slot 6 for the insalltaion of lower layer pipelines is positioned between the low outer cylinder 2 and the inner cylinder 3. The utility model is simultaneously fixed at the position which needs installing drainage pipelines when each storey is cast and compacted with concrete. The utility model is made from corrosion resistant materials, so the utility model has the advantages of high durability, anti seepage and leakage, convenient installation, labor and materials saving, etc.
Description
The utility model relates to the permanent leakproof water draw-off of a kind of pre-buried type, is suitable for building flooring passing through floors central drainage pipe laying and uses.
Reserving hole when the floor casting and compacting of concrete is generally adopted in the draining of building at present, treat again hole to be cut a hole hair after the form removal, fix a drainpipe toward the ditch then or the septic tank discharging, then want one deck to pass through each floor plate for the draining of the kitchen of highrise building, washroom fixes a drainpipe and down arranges with connecing one deck, after treating piping erection, also to water to smash with pea gravel concreten on every side and tamp (generally adopting cement mortar) at pipeline, this method takes a lot of work, time-consuming, expense material, and between new, old concrete and occur seepage easily between as placed concrete and the tube wall.
For addressing this problem, the someone adopts flange form leakproof ring to carry out leakproof, promptly when the pipeline passing through floors is installed, with glue the leakproof ring is cemented on the pipeline in concrete floor, carries out pea gravel concreten again and waters and fill out.This method can only solve the seepage between as placed concrete and the tube wall, can not solve the seepage between the new-old concrete, and maintain when bad when as placed concrete, between the new-old concrete, also the crack can occur between as placed concrete and the pipeline, there is the hidden danger of leaking, also costs the worker simultaneously, take and expect to cut a hole hair, water and fill out pea gravel concreten.
The purpose of this utility model provides the permanent leakproof water draw-off of a kind of pre-buried type, its antiseepage forever, leakproof, and do not need when the floor disturbing concrete reserving hole, cutter hair, water operations such as filling out pea gravel concreten and fix a drainpipe.
Pre-buried type leakproof water draw-off of the present utility model, it is characterized in that it is by inner cylinder, be funnel shaped flange with the inner cylinder one-shot forming, and be connected flange is upper and lower and inner cylinder is coaxial last outer cylinder and following outer cylinder formation, last outer cylinder outer wall offers the concavo-convex closed-loop in 2-4 road and outer cylinder and concrete is spliced firmly form leakproof first, and the lower end edge circumference is drilled with several spilled water holes and does the secondary leakproof; The groove that lower floor's pipeline is installed is arranged between following outer cylinder and the inner cylinder, and the pipe thickness of groove width and lower floor's pipeline matches, and is advisable can assign pipeline.
For strengthening water pouring speed, can make the horn mouth shape with going up the outer cylinder epimere.
For ease of draining and installation, flange becomes 30 to 60 degree to be advisable with the subtended angle of cylinder center's line, and width is got 20-40mm and is advisable, and too little leak resistance is poor, and too big influence is installed.
For reaching the maintenance free purpose of permanent use, the permanent leakproof water draw-off of pre-buried type of the present utility model adopts resistant material (as aluminium alloys, steel, rubber combined, high strength plastics etc.) to make.During making, flange and inner cylinder must one-shot formings, and last outer cylinder and following outer cylinder can connect method with weldbonding and be connected on the flange and make; Also whole device one-shot forming can be made, make at last several spilled water holes of outer cylinder lower end edge circumference jumping chisel again.In order to increase the interior sky of inner cylinder as far as possible, the wall thickness of the inner cylinder attenuate of should trying one's best can insert groove smoothly for ease of lower floor's pipeline during making, and last outer cylinder, the diameter of outer cylinder should suitably strengthen than the diameter of inner cylinder down, has 3-4mm to be advisable to guarantee the groove width.
The permanent leakproof water draw-off of pre-buried type of the present utility model, as long as when each floor casting and compacting of concrete, behind the design position, peripheral floor disturbing concrete and jolt ramming get final product (this device can not have concrete to enter) this device predetermined fixed.When installing one deck water pipe, insert pipeline in the groove from bottom to top, come the upper strata watery diarrhea to advance in following one deck pipeline by flange and inner cylinder, cry the nature leakproof, if produce the crack between last outer cylinder and the concrete, leak when last outer cylinder outer wall down oozes because flange becomes 30 degree to 60 degree subtended angles with the cylinder center line, so water can not past concrete outside seepage, in the row of the leaking inlet pipe road, reach the purpose of secondary leakproof by spilled water hole.
Pre-buried type leakproof water draw-off of the present utility model adopts resistant material to make funnel-shaped design and secondary leak-proof measure.Have advantages such as forever durable, antiseepage, leakproof, simple installation, labor and material saving.
Accompanying drawing is the generalized section of the permanent leakproof water draw-off of the utility model pre-buried type.1 is to go up outer cylinder, the 2nd, following outer cylinder, the 3rd, inner cylinder, the 4th, infundibulate flange, the 5th, spilled water hole, the 6th, groove, the 7th, closed-loop, the 8th, concrete floor among the figure.
Advance the specific embodiments of the permanent leakproof water draw-off of explanation the utility model pre-buried type below in conjunction with accompanying drawing.If the high 100mm of whole device (matching with slab thickness), last outer cylinder 1 height is 48mm, and interior diameter is 114.5mm, wall thickness 1mm; Following outer cylinder 2 height are 50mm, and interior diameter is 114.5mm, wall thickness 1mm; Inner cylinder 3 height are 50mm, and external diameter is 107.1mm, wall thickness 1mm; Flange 4 is 40 degree with the subtended angle of cylinder center's line, wide 30mm, wall thickness 2mm; The diameter of spilled water hole 5 is 2mm, and the spacing between hole and the centerline hole is 2mm; Closed-loop 7 external diameters are 118.5mm, and interior diameter is 116.5mm, ring width 2mm.Whole device adopts aluminum alloy materials to make by above-mentioned size.During making, inner cylinder 3 and flange 4 one-shot formings are made, the coaxial installation of inside and outside cylinder, following outer cylinder 2 is entangled inner cylinder 3 and is welded on flange 4 times, make down and form the wide groove 6 of 3.7mm between outer cylinder 2 and the inner cylinder 3, the outer cylinder 1 that outer wall is offered concavo-convex closed-loop is welded on the flange 4, has evenly bored spilled water hole at 1mm place, last outer cylinder 1 lower end along circumference again and has promptly made the permanent leakproof water draw-off of pre-buried type of the present utility model.It is 114mm that this device is fit to diameter is installed, and wall thickness is the pipeline of 3.2mm.
